DYEING APPARATUS.

Specification of Letters Batent.

Application filed March 3, 1911.

Patented Aug. 12,1913. Serial No. 612,088; l

To alt/whom #may concern.' i

Be it known that I, BERTRAND S. SUM- Mnns, a citizen of the UnitedStates, residing at Port Huron, inthe county of St. Clair and State ofMichigan, have invented certain new and useful Improvements. in DyeingApparatus, of which the following is a specification.

My invention relates more particularly to dyeing vats. and means forsecuring a'proper circulation and supply of liquid thereto. In apparatusofi this character it is essential that the dye be evenly distributedthroughout the material to be treated and that fresh bodies. of: dye becontinually brought into contact with the material treated in order toget: an even hue. of the required depth. Various apparatus has beendevised. for this purpose but none of it completely meets therequirementsof the art.

In my apparatus the liquid is caused to surge through the materialtreated in a vertical direction and at the same time to give a slightlateral motion or displacement thereof. And I further provide means forcontinuously drawing off the liquid-from the bottom of the vat andsupplying itagain at the top thereof, either with or without treatmentof the liquid or additions thereto during its absence from the vat.

The accompanying drawing discloses. a

preferred form of my apparatus, though itwill be apparent from anunderstanding thereof, in connection with the detailed description whichfollows, that various modifications may be made in the apparatus withoutdeparting from the scope of my invention.

The view illustrates the apparatus in a diagrammatic way in sideelevation with certain parts shown in section.

In the particular embodiment shown A refers to a tank which is dividedby a partition B into a dyeing vat C and a chamber D into which theliquid from the dyeing vat may be partially withdrawn, the partition Bbeing cut away near the bottom as at E to provide a passage between thetwo compartments of the tank. The vat C is provided with a perforatedfalse bottom G which extends across the same at a point above theconnection between the compartments D and C and the compartment C isfurther provided with a perforated cover plate H between which and thefalse bottom G the material to be treated is confined.

Cl is a heatingcoil.

Vithin the compartment D a plunger J is arranged to reciprocate looselyand linked by a connecting rod K to an eccentric pin L on a disk M whichmay be rotated for the purpose of reciprocating the plunger. As shown,the chamber D and plunger are rectangular, but it will be evident thatother for-ms might be adopted or the chamber I) formed separate from thevat, in which case it might be cylindrical and if desired a diaphra m besubstituted for the plunger, such modication being obvious equivalentsof the construction shown.

A System of piping leads from the bottom ofthe tank A through the pumpC, shown diagrammatically as of a rotary type, to a point above thetank, the system including pipe connections I?, 2, R, S and T. The lastnamed section is provided at its end with a swiveled section U, which isadapted to be swung from the full line position above the vat C over tothe dotted line position above the compartment D- so that the liquid maybe discharged ldirectly into either the.one compartment or the other. Adrain pipe X is connected to the pipe section P and suitable valves V, Vand V2 are interposed in the positions shown for regulating the flowthrough the various pipes. A storage tank Y is also connected by pipesection Z leading from its bottom with the circulating pipe system asshown, a suitable valve V3 being provided to control the communication,and a return pipe a provided with a valve VA1 leads from t-he dischargeside of the pump to a point above the storage tank Y.

In normal operation the liquid dye is placed in the storage tank Y, theswivel pipe section U swung to the dotted line position over thecompartment D, the valves V3 and V2 opened and the remaining valvesclosed. The pump is then started in operation and the dye dischargedinto the compartment l). By discharging the dye into this compartmentrather than directly into the compartment C the un'evenness which wouldresult from the discharge of the fresh body of dye in one location in acircumscribed area upon thematerial being dyed is avoided. After the dyehas been discharged fl'oni the storage tank Y in sufcient quantity intotank A the valve V is opened and the valve V3 closed, Whereupon in thecontinued. operation of the pump the liquid is withdrawn from the bottomof the tank and discharged into the top of the vat C, the swivel sectionU having been swung over into suitable position for this purpose. If atany time it be de sired to withdraw the liquid from the vat the valve V2may be closed and valve V4 opened, when the continued operation of thepump will discharge the liquid into the storage reservoir Y. I havefound that the operation of the plunger J gives a surging motion to theliquid in the vat C causing itl to rise and fall therein through theperforations in the false bottom G and at the same time giving to thematerial being treated a horizontal motion or jogging, the combinedaction being particularly effective in securing penetration of the dyeto all parts of the material, and this action combined with thecontinuous circulation of the liquid through the pipe system abovedescribed secures great uniformity and quickness of action of the dye.

wWhat I claim is:

l. In an apparatus for subjecting material to the action of a liquid, atank for dyeing substances, means connected with said tank for impartingan up and down motion to the liquid contained therein and for pro ducinga. lateral motion of the contained material, and means for circulatingthe liquor contained in the tank.

2. In apparatus for subjecting material to the action of a liquid, a dyevat, means for causing a surging motion of the liquid therein and othermeans for continuously withdrawing liquid from one part of the vat andsupplying it to another part thereof.

3. In apparatus for subjecting material to the action of a liquid, atank, a partition dividing the tank into a vat and a plunger chamber,there being connection between the vat and the plunger chamber, aplunger in the plunger chamber and means for withdrawing the liquid fromthe botto-m of the tank and supplying it to the top thereof.

4. In apparatus for subjecting material to the action of a liquid, thecombination of a. tank having a partition therein dividing it into a dyevat and a plunger chamber, a plunger working in the plunger chamber, asystem of pipes and a pumpfor withdrawing liquid from the bottom of thetank and discharging it into the top thereof, a storage tank connectedto the system on the suction side ofthe pump and a connection from theexhaust side of the pump to the storage tank for restoring liquidthereto.

5. In an apparatus for subjecting material to the action of a liquid, avat having a substantially vertical -wall at one end, an opening at theother end, and means connected with the opening for forcing a current ofliquid back and forth througl'i said opening, and a perforated bottomlocated above the opening and spaced from the bottom at its juncturewith said Wall whereby the rebound of the liquid from said wall willproduce a to and fro motion of the material being treated.
